用失重法研究了水解聚马来酸酐(HPMA)的缓蚀和分散 性能.结果表明，在HPMA的浓度为50 mg/L渗透剂的浓度为0.5 mg/L有最佳缓蚀效果，缓蚀率为69.3%(80℃).HPMA的分散性能随其浓度的增加而增大，在HPMA的浓度为10.0 mg/L时，其平均分散性能达到630×10-2mg/cm2·h,而在渗透剂T为1.0 mg/L时，平均分散能力达到了6.83×10-2mg/cm2·h.分散性能随Ca2+浓度的增加而减小,在温度为20℃、pH值为6或9时，HPMA分散性能较好.
Effects of temperature,pH value of aqueous solution and the concentration of HPMA and permeat agent on corrosion inhibition and disp ersal properties of HPMA were studied by method of weight loss.The result indicates that the corrosion inhibition efficiency was 69.3% when the concentration of HPMA was 5.0 mg/L and permeate agent was 0.5 g/L.Dispersal ability of water solution increased considerably with the increase of HPMA concentration and decreased with the increase of Ca2+concentration.The addition of permeat agent can improve the dispersal property of HPMA.The optimum dispersal characteristics of water solution was that the concentration of HPMA was 10.0 mg/L,the concentration of permeate agent was 1.0 mg/L, the temperature was 20℃ and the pH value was 6～9.
